PaulAshman Posted January 8, 2008 Report Posted January 8, 2008 This might seem a bit of a stupid question but could someone explain the following to me please: 1. What is the difference between 40's, 45's and 48's? 2. What is the difference between weber and dellorto? 3. And what engine applications is each one best for ie. 1300, 1600 etc? Thanks, Paul.
tim Posted January 8, 2008 Report Posted January 8, 2008 very basicly the number 40/45/48 is todo with the size of the hole the air/fuel goes through. as i understand it,most xflow are good with 40,45s as a min on a pinto
4parajon Posted January 8, 2008 Report Posted January 8, 2008 As ^^^^ has been said, also the difference between Weber & Dellorto is like the difference between Adidas & Nike, they both make the same thing and have followers/critics for both. Not sure if Dellorto are still trading to be honest, I know Weber went through a sticky patch a couple of years ago and no longer turn out the same sort of volumes they did 15-20 years ago, but thats the market for you.
escort21 Posted January 8, 2008 Report Posted January 8, 2008 Bigger the choke size the less bottom end drivability you'll have but more top end
boXXer Posted January 8, 2008 Report Posted January 8, 2008 yeah, but you can over-choke a car. i.e, you cant run 50's on a tiny little 1300 x-flow (unless it revved to 12k! lol) 'Apparantly', dellortos are supposed to make more power as they have a slightly better internal design, how true this is im not sure, but im 90% sure they have gone bust anyway, and the only bits you can get for them are stock parts.
Rich Sav Posted January 8, 2008 Report Posted January 8, 2008 delortos are apparently harder 2 set up as well acording 2 the bloke who done mine stick with webbers
boXXer Posted January 8, 2008 Report Posted January 8, 2008 i thought they were easier, plus they dont go out of sync like webers do.
marky4 Posted January 8, 2008 Report Posted January 8, 2008 peter at sanspeed said delortos were easy to tune up when he did mine and you can still get spares easy from i think southern carbs and don't think there is much to choose from between the 2
Admin Vista Posted January 8, 2008 Admin Report Posted January 8, 2008 As ^^^^ has been said, also the difference between Weber & Dellorto is like the difference between Adidas & Nike, they both make the same thing and have followers/critics for both.Not sure if Dellorto are still trading to be honest, I know Weber went through a sticky patch a couple of years ago and no longer turn out the same sort of volumes they did 15-20 years ago, but thats the market for you. I guess that's because the market isn't there any more except for with us die hard induction noise lovers. Engine management systems and throttle bodies have taken over and give better results, plus how many new cars still come with carbs? I don't know of any.
MexDan Posted January 8, 2008 Report Posted January 8, 2008 I cant think of any current production cars that have carbs on them any more , fuel injection is a much more efficient method for every day drivers and doesnt need nearly as much setting up and tinkering with throughout a cars life.. One difference between webers and dellortos is the adjustment screws, there are many more threads which are also closer together on a delorto which apparently allow for a greater degree of fine tuning... For a 1.3 or 1.6 i would go with 40's.. although you do see 1.6's with 45's. I run 40's on my 1.6 xflow which have always been pretty easy to setup
Guest MK1gaz Posted January 9, 2008 Report Posted January 9, 2008 Yes you can use/get webers , delortos , solex's etc and there's not much between them and THEY ALL SOUND GREAT . The new Spanish made webers are crap compared to the old ones though so watch out for those .

Guest MK1gaz Posted January 9, 2008 Report Posted January 9, 2008 Ask Wayne at W.P.E. , he's had grief with the new spanish webers that are floating about
marky4 Posted January 9, 2008 Report Posted January 9, 2008 whats the difference between the old and new types? the build quality is not as good as the old one's

w p e Posted January 9, 2008 Report Posted January 9, 2008 inferior made parts is the main trouble with spanish ones but now there back in italy so all should be good. webcon do a set witch burtons are trying to sell but no one does a linkcage for them. there realy SK racing made in the usa. there a cross between webber & dellorto ive got some and think there the bo-----s with built in fuel regulater and built in float adjustment screw
X-pack-Glyn Posted January 10, 2008 Report Posted January 10, 2008 A bit like lambretta's, if you cant afford a genuine italian one you end up with a shity indian built one that falls to bits...
Toby Posted January 11, 2008 Report Posted January 11, 2008 This might seem a bit of a stupid question but could someone explain the following to me please: 1.

This is pretty informative. I think a lot of it is semi copied from the webber book The graph a little way down the page is a picture saying a thousand words!! And then read the paragraph just above the graph.
